Stocks to watch on Tuesday:Synergy Pharma (SGYP) and Novavax (NVAX) - both biotech stocks rallied 9% on Monday due to excitement surrounding M&A activity in the sector. No indication exists that either Synergy Pharma or Novavax has interested suitors or would willing to accept a deal. The stock likely gives up these gains. Twitter (TWTR) - the social media stock dipped 1.4% on the news of COO Noto being offered the SoFi CEO job. Keeping Noto remains a prime focus of this week with the only reason that Noto leaves is that Twitter is for sale considering he is already the defacto CEO of Twitter. Buy any dips unless Noto does actually leave. Netflix (NFLX) - the streaming leader added a bunch of subscribers. The company burned $2 billion last year, but the market will buy the stock regardless. Netflix remains hard to own, but one that likely heads higher and higher.
